Description

Technical Field

[0001] The invention belongs to process scheme design, and specifically is a ventilating method for lubricating oil pipelines. Background Art

[0002] Lubricating oil is often used in industrial manufacturing. As a result, fluid flow in fluid pipelines can introduce a significant amount of air, reducing flow and even causing air blockage. Furthermore, due to the high viscosity of the fluid, air cannot automatically escape from the tank due to buoyancy, ultimately leading to a significant amount of air in the pipeline, severely impacting the flow of lubricating oil. Therefore, a lubricating oil pipeline ventilation solution is needed to promptly expel air from the pipeline to ensure fluid flow.

[0003] Therefore, a ventilation method for lubricating oil pipelines is designed here to solve the above problems. Summary of the Invention

[0004] The object of the present invention is to provide a method for ventilating a lubricating oil pipeline to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a ventilation method for a lubricating oil pipeline.

[0006] In a further embodiment, this embodiment provides a method for ventilating a lubricating oil pipeline, comprising a lubricating oil storage cabinet, a liquid outlet pipeline, a lubricating oil body, a support rod, and an electric push rod. The liquid outlet pipeline is fixedly connected to one side of the lubricating oil storage cabinet, the lubricating oil body flows inside the liquid outlet pipeline, the support rod is fixedly connected to the surface of the liquid outlet pipeline, and the electric push rod is fixedly connected to the surface of the support rod. The ventilating method for the lubricating oil pipeline comprises the following steps:

[0007] A1. Air flows back into the lubricating oil storage tank through the liquid outlet pipe, and then is discharged upward due to buoyancy.

[0008] A2. Activating the venting device of the lubricating oil pipeline allows the air generated by the flow of the main lubricating oil in the liquid outlet pipeline to be discharged in a timely manner. Because the air only needs to flow back through the smaller amount of lubricating oil in the liquid outlet pipeline, the resistance is greatly reduced, so the air can be discharged in a timely and effective manner, avoiding the phenomenon of blockage of the liquid outlet pipeline.

[0009] The ventilation device of the lubricating oil pipeline used in step A2 includes a piston mechanism, a sliding mechanism and a connecting mechanism. The piston mechanism includes a piston mounting shell, a rotating sealing disk and a connecting rod. The surface of the liquid outlet pipeline is fixedly connected to the piston mounting shell. The piston mounting shell and the inner wall of the liquid outlet pipeline are rotatably connected with a rotating sealing disk. A connecting rod is slidably installed inside the piston mounting shell. The sliding mechanism is symmetrically fixedly connected to the surface of the piston mounting shell. The connecting mechanism is fixedly installed at the bottom of the electric push rod. The lubricating oil body inside the liquid outlet pipeline carries air toward the lubricating oil storage cabinet. The excess air inside the liquid outlet pipeline is extracted through the piston mechanism. The rotating sealing disk cooperates with the connecting rod to facilitate the discharge of air inside the liquid outlet pipeline. The sliding mechanism facilitates the timely discharge of air from the inside of the piston mounting shell. The connecting mechanism facilitates the connection of the connecting rod and the electric push rod. The connecting rod is pulled mechanically without the need for manual pulling of the connecting rod.

[0010] Preferably, a mounting frame is fixedly connected to the bottom of the lubricating oil storage cabinet to provide stable support for the lubricating oil storage cabinet, ensuring that the lubricating oil storage cabinet will not shake easily during use, preventing the bottom of the lubricating oil storage cabinet from directly contacting the ground, and reducing wear on the bottom of the lubricating oil storage cabinet.

[0011] Preferably, the piston mechanism also includes a piston extrusion block, a gas filter membrane, a semicircular groove and a marking block. The inner wall of the piston mounting shell is slidably connected to the piston extrusion block, and the piston extrusion block is fixedly connected to the bottom end of the connecting rod. The inner wall of the piston mounting shell is fixedly connected to the gas filter membrane, a semicircular groove is provided on the surface of the rotating sealing disk, and a marking block is fixedly connected to the surface of the rotating sealing disk. Tiny pores are equidistantly provided on the semicircular surface of the gas filter membrane. The rotating sealing disk is rotated to align the semicircular groove and the opening position of the gas filter membrane. The connecting rod is pulled upward to drive the piston extrusion block to move upward, and air enters the interior of the piston mounting shell. The rotating sealing disk is rotated in the opposite direction to block the opening position of the gas filter membrane. The sliding mechanism is slid, and the connecting rod is pressed downward. The piston extrusion block discharges the air inside the piston mounting shell through the sliding mechanism.

[0012] Preferably, the sliding mechanism includes a sliding connection seat, a sliding connection groove, a vent, a slider and a first return spring. The sliding connection seat is symmetrically fixedly connected to the surface of the piston mounting shell. A sliding connection groove is provided inside the sliding connection seat. An vent is provided on the inner wall of the sliding connection groove, and the vent is communicated with the inner wall of the piston mounting shell. A slider is slidingly connected inside the sliding connection groove. The inner wall of the sliding connection groove is fixedly connected to the first return spring, and the slider and the first return spring are fixedly connected. Sliding the slider will send the slider into the sliding connection groove, the first return spring is squeezed and tightened, and the air inside the piston mounting shell is discharged from the vent. Release the slider, the first return spring returns to its original position and opens, and the slider reseals the vent.

[0013] Preferably, the sliding mechanism also includes a driving block, and the driving block is fixedly connected to the surface of the first return spring, which makes it convenient for fingers to press the driving block to drive the slider to move and send the slider into the sliding connection groove, thereby facilitating and quickly driving the slider.

[0014] Preferably, the connecting mechanism includes a first connecting seat, a second connecting seat, a limiting ring, and a connecting block. The top of the connecting rod is fixedly connected to the first connecting seat, the bottom of the electric push rod is fixedly connected to the second connecting seat, the top of the first connecting seat is symmetrically fixedly connected to the limiting ring, and the bottom of the second connecting seat is fixedly connected to the connecting block. The connecting mechanism also includes a pressing block and a second return spring. The pressing block is symmetrically and slidingly connected to the inner wall of the connecting block, and the second return spring is symmetrically and fixedly connected to the inner wall of the connecting block. The pressing block and the second return spring are fixedly connected. The electric push rod drives the second connecting seat close to the first connecting seat, and the connecting block closes to the limiting ring. The pressing block is squeezed by the limiting ring and enters the interior of the connecting block. The second return spring is squeezed and contracts, and the connecting block is pressed against the top of the first connecting seat. The second return spring resets and expands, sending the pressing block into the interior of the limiting ring, thereby connecting the connecting rod and the bottom end of the electric push rod.

[0015] Preferably, the edge of the pressing block is provided with rounded corners, so that when a finger presses the pressing block, the finger will not be easily scratched by the edge of the pressing block, thereby improving the safety of the pressing block.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By installing the piston mechanism, sliding mechanism and connecting mechanism, the air generated by the flow of the lubricating oil body can be effectively discharged to prevent the air from entering the lubricating oil storage cabinet, making the air discharge simple and fast, ensuring that the liquid flow can meet the use requirements, so that the lubricating oil can effectively play its role, such as cooling, lubrication, etc., reducing safety hazards.

[0018] 2. A mounting bracket is fixedly connected to the bottom of the lubricating oil storage cabinet to provide stable support for the lubricating oil storage cabinet, ensuring that the lubricating oil storage cabinet will not shake easily during use, preventing the bottom of the lubricating oil storage cabinet from directly contacting the ground, and reducing wear on the bottom of the lubricating oil storage cabinet.

The ventilating method for the lubricating oil pipeline comprises the following steps:

[0028] A1. Air flows back into the lubricating oil storage tank 1 through the liquid outlet pipe 2, and then is discharged upward due to buoyancy.

[0029] A2. Activating the oil pipeline's breather device allows air generated by the flow of oil main body 3 in liquid outlet pipeline 2 to be promptly discharged. This is because air only needs to flow countercurrently through a smaller amount of oil main body 3 in liquid outlet pipeline 2, significantly reducing resistance. Therefore, air can be discharged promptly and effectively, preventing blockage of liquid outlet pipeline 2.

[0030] The ventilation device of the lubricating oil pipeline used in step A2 includes a piston mechanism 4, a sliding mechanism 5 and a connecting mechanism 6.

The connecting mechanism 6 is fixedly installed at the bottom of the electric push rod 8. The lubricating oil main body 3 inside the liquid outlet pipeline 2 carries air toward the lubricating oil storage cabinet 1. The excess air inside the liquid outlet pipeline 2 is extracted through the piston mechanism 4. The rotating sealing disk 42 cooperates with the connecting rod 43 to facilitate the discharge of air inside the liquid outlet pipeline 2. The sliding mechanism 5 facilitates the timely discharge of air from the inside of the piston mounting shell 41. The connecting mechanism 6 facilitates the connection of the connecting rod 43 and the electric push rod 8.
